    A hole in an ancient cow’s skull could have been surgery practice

    Ancient surgeons may have practiced dangerous skull-opening procedures on cows before operating on people.

    A previously excavated cow skull from a roughly 5,400- to 5,000-year-old settlement in France contains a surgically created hole on the right side, a new study finds. No signs of bone healing, which start several days after an injury, appear around the opening. One or more people...

    A new plastic film glows to flag food contaminated with dangerous microbes

    Pathogen detectors built into plastic patches could someday spare you food poisoning.

    Carlos Filipe, a chemical engineer at McMaster University in Hamilton, Canada, and colleagues have developed a new kind of flexible film that’s coated in molecules that glow when they touch E. coli cells. This type of sensor also glows in the presence of molecules secreted by E. coli, so the material...

    Should you bank your baby’s umbilical cord blood? Here’s a guide for thinking through the issue.

    With the promise and pitfalls of umbilical cord blood samples in mind, how should parents decide whether to put their baby’s blood on ice, either for their own family’s future use or as a donation for the greater good? It’s a tricky calculation, one that changes based on a family’s risk threshold, dreams for the future and, of course, money.

    Instead of floundering about aimlessly, let’s...

    Finger fossil puts people in Arabia at least 86,000 years ago

    A single human finger bone from at least 86,000 years ago points to Arabia as a key destination for Stone Age excursions out of Africa that allowed people to rapidly spread across Asia.

    Excavations at Al Wusta, a site in Saudi Arabia’s Nefud desert, produced this diminutive discovery. It’s the oldest known Homo sapiens fossil outside of Africa and the narrow strip of the Middle East that...

    Fossils sparked Charles Darwin’s imagination

    Darwin’s FossilsAdrian ListerSmithsonian Books, $19.95

    Charles Darwin famously derived his theory of evolution from observations he made of species and their geographic distributions during his five-year voyage around the world on the H.M.S. Beagle. But in the introduction of On the Origin of Species, the naturalist also cites another influence: the thousands of fossils that he...

    Readers debate dinosaur designation and more

    Diagnosis dinosaur

    Some scientists are shaking up the dinosaur family tree and raising questions about which features define the ancient reptiles, Carolyn Gramling reported in “New fossils are redefining what makes a dinosaur” (SN: 3/3/18, p. 18).

    “I am a bit put out by the continuing references to dinosaurs as being reptiles,” reader David Persuitte wrote. Dinosaurs’ legs were...

    Flying insects tell tales of long-distance migrations

    Every autumn, a quiet mountain pass in the Swiss Alps turns into an insect superhighway. For a couple of months, the air thickens as millions of migrating flies, moths and butterflies make their way through a narrow opening in the mountains. For Myles Menz, it’s a front-row seat to one of the greatest movements in the animal kingdom.

    Menz, an ecologist at the University of Bern in...

    Are we ready for the deadly heat waves of the future?

    Some victims were found at home. An 84-year-old woman who’d spent over half her life in the same Sacramento, Calif., apartment died near her front door, gripping her keys. A World War II veteran succumbed in his bedroom. Many died outside, including a hiker who perished on the Pacific Crest Trail, his water bottles empty.

    The killer? Heat. Hundreds of others lost their lives when a...

    How physicists will remember Stephen Hawking

    Stephen Hawking, a black hole whisperer who divined the secrets of the universe’s most inscrutable objects, left a legacy of cosmological puzzles sparked by his work, and inspired a generation of scientists who grew up reading his books.

    Upon Hawking’s death on March 14 at age 76, his most famous discovery — that black holes aren’t entirely black, but emit faint...
